It is believed, however, that the great purposes for the attainment of which the Federal Government was instituted have not been lost sight of. Intrusted only with certain limited powers, cautiously enumerated, distinctly specified, and defined with a precision and clearness which would seem to defy misconstruction, it has been my constant aim to confine myself within the limits so clearly marked out and so carefully guarded. Having always been of opinion that the best preservative of the union of the States is to be found in a total abstinence from the exercise of all doubtful powers on the part of the Federal Government rather than in attempts to assume them by a loose construction of the Constitution or an ingenious perversion of its words, I have endeavored to avoid recommending any measure which I had reason to apprehend would, in the opinion even of a considerable minority of my fellow-citizens, be regarded as trenching on the rights of the States or the provisions of the hallowed instrument of our Union. Viewing the aggregate powers of the Federal Government as a voluntary concession of the States, it seemed to me that such only should be exercised as were at the time intended to be given. I have been strengthened, too, in the propriety of this course by the conviction that all efforts to go beyond this tend only to produce dissatisfaction and distrust, to excite jealousies, and to provoke resistance. Instead of adding strength to the Federal Government, even when successful they must ever prove a source of incurable weakness by alienating a portion of those whose adhesion is indispensable to the great aggregate of united strength and whose voluntary attachment is in my estimation far more essential to the efficiency of a government strong in the best of all possible strength--the confidence and attachment of all those who make up its constituent elements. Thus believing, it has been my purpose to secure to the whole people and to every member of the Confederacy, by general, salutary, and equal laws alone, the benefit of those republican institutions which it was the end and aim of the Constitution to establish, and the impartial influence of which is in my judgment indispensable to their preservation. I can not bring myself to believe that the lasting happiness of the people, the prosperity of the States, or the permanency of their Union can be maintained by giving preference or priority to any class of citizens in the distribution of benefits or privileges, or by the adoption of measures which enrich one portion of the Union at the expense of another; nor can I see in the interference of the Federal Government with the local legislation and reserved rights of the States a remedy for present or a security against future dangers.
